The present 'invention relateseto certain new and useful grease-gun-loading pail-base or pump-loading pail-base, for receiving, at itsgtop, an original and relatively thin-walled and inexpensive vendable merchandising container (namely, a container in which the fluid or semi` fluid is originally packed, shipped, storedand sold), as, for instance, an originalthin-walled sheet-metal pail of lubricant (such as grease or viscous 011)..01' of printers" ink, caulkingeompound, etc., andA for receivingfateits side,v the reservoirebarrel of a grease-gun or the like or a pump-cylinder, whereby the lubricant or other:

viscous uid` may be convenientlyloadeddirectly from the original container intothe reservoirbarrel ofthe grease-gun or into the pumpcylinder through the intervention of the gunloading pail-base of the' present' invention.

One of the. further objects of thepresent invention is to provide` a gun-loading. pail-base or transfer-base similar tothe vpail-bases or transfer-bases, but which will bei adapted to receive and to operate with a standard pail or can with for the purpose of illustrating my invention,v

forms thereof which are at present preferred,v

although it is to be understoodgthat the various instrumentalities of which the invention consists can be variously arranged` and organizedand that the invention is not limited to the` precise arrangements and organizations of the instrumentalities as herein shown and described. Y

In the accompanying drawings, in which like reference characters indicate like parts,

Figure 1 represents a fragmentary,l vertical cross-sectional view of a pail-base or transferbase embodying the present invention with a fragmentary portion of a can depressed thereon in operative relation thereto.

Figure 2 represents a similar fragmentary vertical cross-sectional view, another embodiment of the present invention.

Figure 3 represents a vertical cross-sectional view oi a modified form of can-gripping member.

Figure 4 vrepresents al vertical'cross-sectional view of another can-gripping member of a modiiled form of construction embodying the present invention.

In` the drawings, the pail or can is generally designated by the' letter C, while the base is generally designated by the letter B.

The bottom fil-a' ofthe container C, is provided with 'a downwardlydepending more or less cylindricalflange-like portionv II-b, which tele*- scopes into the lower end of the cylindrical body' Il-d of the container C; to a greater or lesser extent, dependingwupon the axial length of flange l l-b, and is secured thereto Vby anv interlocking. crimped seamll-c.

- The sheet-metal bottomV ll-w, of the container C may have pressed 'into' it, in a downward direction (orvin anv upward direction) ,anannular-groove 23, tov form ka doughnut-like ridge or annulus on` the outside (or on the inside) 'of the bottom il-a; theouter` (orinner) more or less nat or rounded annulus-like surface 24' of'which constitutes a seatinglsuriacefor making sealingcontact with `an annular sealing-gasket or ring 25` (of cork, grease-resistant rubber or composition or other suitable resilient material) carried by the base` BH The annulus 23 is preferably centered, or approximately centered, in relation to theperiphery ofthe bottom ll-a of the con-` tainer C.

' Ther annulus=23-also serves to stiften the center ofthel bottom l li-a, sotliat a circular disc-like portion, within: the center of the annulus 23, can bev-more readily cut out or'knocked out by the cutting action of the cutters (asin the embodi= ment Vherein shown and described) or by any other suitable disc-removal operation. The annulus 2'3 also serves to center or guide the cutters serves also to stiften and reinforce the center ofk the `bottom l'I--al after the disc or4 removed therefrom;

r.In one-embodiment' of the base oi my present invention; illustrated in the drawings, the base BU lmay .be .formed of two4 members, 22-cl and 22-b, which may be Welded to each other or may be interlockedby a seam29, so as to form a generallyunitary construction, in which each membeisupports and gives rigidity to the other, thereby permitting the two membersto be formed (bypressing between'. dies or by spinning or by rolling, or thelike) out Vofrelatively thin sheetsteel as, for instance, 20 or 22 gauge sheet-steel for a basefor a, 25` lb. container, or -otherrelatively thin sheet-metaLand yet maintaining` adequate-strengthvand rigidity in the iinished base (IBI). A v

Inthe end-wall orfbottom 22, a center aperture 3l is formed, and the material from the has been out out aperture 3l may be pressed or drawn upwardly to form a short upstanding tube-like cuttersupporting intake-flange or intake member 32, although this tube-like cutter-supporting intakefiange or intake member is preferably formed separately, as'shown, in the drawings, and spotwelded or crimp-seamed to the wall surrounding the aperture 3l. The metal around the hole 3l may be pressed down in a downwardly extending annulus 33, forming an annular groove;

` 'telescoped over the rod 2 and an upper terminal around the tube-like flange 32, forrthe reception and retention of the resilient andg-rease-resistant packing gasket or sealing-ring 25.

From the partition-wall or bottom 22,. a

radial channel 34, of more or less U-shaped crosssection, is pressed, in a downwardgdirection, from a point which includes the projected area of the hole 3I (and may also include the projected areaof the annulus 33), which channel 34 extends laterally outwardly to the side-wall 30, at one point, so as to form a fluid-conducting passageway or conduit in communication with the hole receiving socket 36 formed in or Aaffixed tothe side of the base B.

The base may be of a general construction with two or three anchorage members I which may be a form of eyelet or eyebolt extending through the wall of the base, as indicated in Figures 1 and 2, or it may be an anchorage formed integrally with the base or welded thereto.

'Io these anchorages I, preferably uniformly distributed around thev periphery of the base clamping rods 2, are'loosely, and preferably pivotally secured in the manner indicated in Figure 1, and these rods may either be continuous or articulated as indicated at 3, by rinterlinkingin chain fashion two shorter rods.v

The upper end of the rod is preferably threaded as at 4, and a sleeve 5 having a rim-engaging claw 6, is telescoped over the threaded end 4 of the rod, and above it a wing-nut or other suitable threaded member 1 is threaded securely to the rod.

After the can C has been perforated and an opening cut in the bottom thereof by means of the cutter 25 carried by the base, the rim-engaging claws 6 are hooked over the rim 8 of the lid In Figure 2 continuous helical tension springs,

9 are linked to the anchorages, and to their upper ends bead engaging members II) are linked, having handle portions I I and rim-engaging portions By pulling member I0 upwardly and hooking it over the rim, the can can be held rmly to` the base after the opening has been established in the bottom thereof.

In Figure 3 a modified form of construction is shown in which a sleeve I3 is placed loosely andv slidingly over the rod 2 near the upper end thereof, and a rim-engaging claw I4 provided on one side of the sleeve and a handle member or fingergripping member I5 on the other side thereof, a helical compression spring interposed between the top of the sleeve I3 and a terminal abutment Il 4affixed to the upper end of .the rod 2; the

.spring .abutment .IJ carried thereby, and the spring I6 is interposed between the abutment I1 and the inturned end or closed end I9 of the tube la.

A-rim-engaging member 20 is secured to the upper end ofthe tube I8 by being threaded thereto ,or otherwiselsecured thereto and having a handle portion 2I by which it can be raised to hook the member 2t) over the rim of the can; the spring I6 thereafter serving to hold the can firmly against the base.
